         4 . The specimen-containing unit of  claim 1 , wherein a direction of the containment hole corresponds to a tangential direction of an imaginary circle formed by an end portion of the extension portion as the extension portion rotates with rotation of the body portion. 
     
     
         5 . The specimen-containing unit of  claim 1 , wherein the specimen-containing unit is formed so that widths of the extension portion and the specimen containment portion correspond to each other. 
     
     
         6 . The specimen-containing unit of  claim 1 , wherein the specimen containment portion is formed integrally with the extension portion. 
     
     
         7 . A specimen measurement unit comprising:
 the specimen-containing unit defined in any one of  claims 1  to  6 ; and   a specimen measurement cassette comprising a first accommodation portion configured to store a first reagent in which the specimen containment portion is dipped to react with the specimen, a second accommodation portion partitioned from the first accommodation portion and configured to store a second reagent, and a measurement portion configured to assay results obtained by reaction of the specimen with the first reagent.   
     
     
         8 . The specimen measurement unit of  claim 7 , wherein the measurement portion is configured to accommodate the second reagent after a predetermined time has elapsed, after the first accommodation portion accommodates the specimen reacting with the first reagent. 
     
     
         9 . The specimen measurement unit of  claim 7 , wherein the inflow of the first reagent and the second reagent into the measurement portion is implemented by self-loads of the first reagent and the second reagent. 
     
     
         10 . The specimen measurement unit of  claim 7 , wherein the first reagent and the second reagent are prevented from flowing outwards by a first foil tap and a second foil tap configured to close bottom surfaces of the first accommodation portion and the second accommodation portion, respectively, and
 the first foil tap and the second foil tap are shifted from the bottom surfaces of the first accommodation portion and the second accommodation portion, respectively, by a specimen measurement device having the specimen measurement cassette installed therein to assay results obtained by reaction of the specimen with the first reagent and the second reagent, so that the first reagent and the second reagent flow into the measurement portion.   
     
     
         11 . The specimen measurement unit of  claim 10 , wherein each of the first foil tap and the second foil tap is arranged so that one end of each of the first foil tap and the second foil tap is bent toward the other end. 
     
     
         12 . The specimen measurement unit of  claim 7 , further comprising an absorption portion disposed under the measurement portion to absorb a mixture of the specimen in which the results obtained by reaction of the specimen with the first reagent are completely assayed. 
     
     
         13 . The specimen measurement unit of  claim 7 , wherein the reaction of the specimen with the second reagent is implemented at the measurement portion. 
     
     
         14 . A specimen measurement device comprising:
 the specimen measurement unit defined in  claim 10 ; and   a specimen measurement body having the specimen measurement cassette installed therein, configured to assay results obtained by reaction of the specimen with the first reagent and the second reagent, and comprising an external force application portion configured to apply an external force to shift the first foil tap and the second foil tap from bottom surfaces of the first accommodation portion and the second accommodation portion, respectively.   
     
     
         15 . The specimen measurement device of  claim 14 , wherein the external force application portion applies the external force to one side end of the first foil tap and one side end of the second foil tap, respectively, in opposite directions.
